What is the International Data Encryption Algorithm (IDEA)? The International Data Encryption Algorithm (IDEA) is a symmetric key block cipher encryption algorithm designed to encrypt text to an ...

The National Security Agency (NSA) is offering two families of encryption algorithms, known as block ciphers, intended to provide a level of security for such processes as authentication or ...

Zero-correlation linear cryptanalysis is an important method to analyze the security of block ciphers. But there are few works on zero-correlation linear attacks combined with the related-key setting.

In my blog “The Importance of Memory Encryption for Protecting Data in Use,” I discussed the growing industry consensus on the imperative of incorporating memory encryption in computing architectures.
